Start with the air and the work
Learning objective: Explain why the task needs protection and who sets the work limits.
A worker is about to grind a coated part. The dust collector is down. A box of respirators sits nearby. The box does not make the task ready. The team must review the air hazard, restore needed controls and confirm the work plan.
A respirator is a device that helps protect you from a specific breathing hazard. It works only when it suits the hazard and is used in the right way. Poor fit, wrong use or poor care can let harmful air reach you.
The employer must use feasible engineering controls to limit airborne harm. These can include enclosure, local exhaust or a safer material. Respirators are needed when suitable controls are not feasible, while controls are being put in place, or when the rules otherwise require them. They do not cancel other required controls.
The employer runs a written program for required use. A program administrator oversees it. Ask who that person is and how to reach them. The employer provides required respirators, training and medical evaluations at no cost to you.
